Missing Month totals in Sales invoice by item totals Report

@lubos In my Manager, I have generated sales invoice totals by item report for the financial year 2017-18. But the system has shown the month-wise totals from Apr-17 to Feb-18, In the March month column system has shown the year totals instead of Mar.18 month totals.

Mar dates are 01/03/2017 and not 2018!

thanks @Joe91.
